Background Cerebral vasospasm (CV) is a major cause of delayed morbidity and mortality in patients with subarachnoid hemorrhage (SAH). Various cerebral protectants have been tested in patients with aneurysmal SAH. We aimed to research the success rate of treatment of CV via intra-arterial milrinone injection and aggressive pharmacological therapy for refractory CV. Methods A total of 25 consecutive patients who received intra-arterial milrinone and nimodipine treatment for CV following SAH between 2014 and 2017 were included in the study...

Reversible cerebral vasoconstriction syndrome (RCVS), also known as Call-Fleming syndrome, is one of the rare causes of thunderclap headaches, which are most often seen in females aged 20-40 years and which can cause neurological deficits. The cause of RCVS is thought to be multifocal arterial constriction and dilatation caused by transient disregulation of cerebral vascular tonus. Presently described is case of 63-year-old female patient who presented with complaint of sudden onset of recurrent headaches located on the left side...

Over the past 2 decades, a large number of guidelines for aneurysmal subarachnoid hemorrhage (aSAH) management have been proposed. The primary aim of these "evidence-based" guidelines is to improve the care of aSAH patients by summarizing and making current knowledge readily available to clinicians. However, an investigation into aSAH guidelines, their changes along time and their successful translation into clinical practice is still lacking.We performed a literature search of historical events and subarachnoid hemorrhage guidelines using the Entrez PubMed NIH, Embase, and Cochrane databases for articles published up to November of 2016...

Reversible cerebrovascular vasoconstriction syndrome is an uncommon condition that presents as severe headache and hypertension. Recent literature suggests a 1% incidence in postpartum headache cases. It can cause subarachnoid hemorrhages, cerebral ischemia, and seizures. It is often misdiagnosed as postdural puncture headache or preeclampsia. In this case, a postpartum woman, who had received epidural anesthesia for labor, presented 5 days postpartum with severe headache that did not resolve with an epidural blood patch...

BACKGROUND: Long-term continuous intra-arterial nimodipine infusion (CIAN) is a rescue therapy option in cases of severe refractory cerebral vasospasm (CV) following acute non-traumatic subarachnoid hemorrhage (SAH). However, CIAN therapy can be associated with relevant side effects. Available studies focus on intracerebral complications, whereas extracerebral side effects are rarely examined. Aim of the present study was to generate descriptive data on the clinical course during CIAN therapy and expectable extracerebral side effects...

INTRODUCTION: We sought to determine whether compliance with scheduled nimodipine in subarachnoid hemorrhage patients impacted patient outcomes, with the intent of guiding future nimodipine management in patients who experience nimodipine-induced hypotension. METHODS: We performed a retrospective analysis of 118 consecutive aneurysmal subarachnoid hemorrhage patients treated with the Maryland Low-Dose IV Heparin Infusion Protocol. Patients were categorized into three independent nimodipine compliance groups: ≥1 dose held, ≥1 dose split, and no missed or split-doses...

BACKGROUND: Cerebral vasospasm leading to delayed cerebral infarction (DCI) is a central source of poor outcome in patients with aneurysmal subarachnoid hemorrhage (aSAH). Current treatments of cerebral vasospasm are insufficient. Cisternal blood clearance is a promising treatment option. However, a generally applicable, safe, and effective method to access the cisterns of the brain is lacking. OBJECTIVE: To report on stereotactic catheter ventriculocisternostomy (STX-VCS) as a method to access the cisterns of the brain for clearance of subarachnoid hemorrhage in patients with aSAH and coiled aneurysms...

Nimodipine is well characterized for the management of aneurysmal subarachnoid hemorrhage and has been shown to promote a better outcome and less delayed ischemic neurological deficits. Animal and clinical trials show neuroprotective efficacy following nerve injuries. We showed a neuroprotective effect on Neuro2a cells. Subsequent microarray analysis revealed-among others-fatty acid 2-hydroxylase (FA2H) upregulated by nimodipine in vitro, which is a component of myelin synthesis. Differentiated Neuro2a cells were analyzed for nimodipine-mediated survival considering stress treatment in comparison to nifedipine-treatment...

Reversible cerebral vasoconstriction syndrome (RCVS) is a rare but increasingly recognized disorder with over 500 cases published in the literature. The condition is characterized by recurrent severe thunderclap headaches with or without other neurological symptoms and diffuse segmental narrowing of the cerebral arteries which is reversible within 3 months. RCVS may occur spontaneously but in over 50% of cases, it is associated with various other conditions, including vasoactive medications or illicit drugs and the post-partum state...

BACKGROUND: Oral nimodipine is an established prophylactic agent for cerebral vasospasm after subarachnoid hemorrhage (SAH). In highly selected cases, intra-arterial (IA) or intravenous (IV) application of nimodipine may be considered; however, the optimum dosage and modality of application remain a matter of debate. The purpose of this investigation is analysis of nimodipine concentration in serum, cerebrospinal fluid, and cerebral microdialysate in the context of currently effective dose and route of application (oral, IA, IV)...

BACKGROUND: Clinically symptomatic vasospasm leading to delayed ischemic neurological deficits occurs in up to 30% of patients with subarachnoid hemorrhage (SAH). Vasospasm can result in a serious decline in clinical conditions of patients with SAH, yet the algorithm for vasospasm treatment and prevention remains unclear. Intra-arterial administration of vasodilators is one of the modalities used for vasospasm therapy. METHODS: Over the last 7 years, we have treated 27 female and 7 male patients with vasospasm using intra-arterial administration of either nimodipine or milrinone; all had suffered aneurysm rupture...

Spontaneous subarachnoid hemorrhage (SAH) affects people with a mean age of 55 years. Although there are about 9/100 000 cases per year worldwide, the young age and high morbidity and mortality lead to loss of many years of productive life. Intracranial aneurysms account for 85% of cases. Despite this, the majority of survivors of aneurysmal SAH have cognitive deficits, mood disorders, fatigue, inability to return to work, and executive dysfunction and are often unable to return to their premorbid level of functioning...

COMPARATIVE STUDY
Hassan M Rashed, Rehab N Shamma, Emad B Basalious
Nimodipine (NM) is the only FDA-approved drug for treating subarachnoid hemorrhage induced vasospasm. NM has poor oral bioavailability (5-13%) due to its low aqueous solubility, and extensive first pass metabolism. The objective of this study is to develop radiolabeled NM-loaded LPM and to test its ability prolong its circulation time, reduce its frequency of administration and eventually target it to the brain tissue. NM was radiolabeled with (99m)Tc by direct labeling method using sodium dithionite. Different reaction conditions that affect the radiolabeling yield were studied...

REVIEW
U Jaschinski
Aneurysmal subarachnoid hemorrhage (SAH) is a devastating disease and nearly one third of patients die in the acute phase. Due to the bleeding event, a hyperactive sympathetic nervous system and an uncontrolled inflammatory response have a profound local and systemic impact on other organ functions. Neuroendocrinological disorders and cardiopulmonary morbidity are dominant. Despite a decrease in hospital mortality for high volume centers, a high proportion of survivors suffer from neurological deficits. Knowledge of the pathophysiology of vasospasms in the later stages of the disease has increased...
